IMPROVEMENT IN WHEEL-PRESS.

Specification forming part of Letters Patent No. 35,127, dated April 29,1862.

To all whom it may concern:

Be it known that I, COLEMAN SELLERS, of

Philadelphia in the State of Pennsylvania,

have invented a new and Improved Wheel- Press and I do hereby declarethe following to be a full and exact description thereof.

The object of my invention is to simplify the construction of permanentforcing-inachines, used principally in the construction of railwaymachinery, and technically called wheel-presses, so as to enable thesame upright to be used either for pushing on or pullin g off wheelsfrom their axles.

The nature of my invention consists in the use of a permanent upright,on which is arranged the forcing machinery in connection with anadjustable upright capable of being readily moved into position for thework re quiredto be done. t

The manner of accomplishing this can be understood by reference to theaccompanying drawing, making part of this specification, and whichrepresents a side elevation of one of my improved presses.

The permanent upright A, securely fastened to a foundation of masonry,is provided in its centr with a ram or plunger, B, working in acylinder, thus forming a powerful hydrostatic press. The power isconveyed to this press through the pipe 0, which is connected with anyordinary pumping machinery, or the plunger B may be operated by a screw,if considered preferable. 'A second permanent upright, E, also bolted tofoundation, is placed at a convenient distance from the upright A, andis designed only to hold in position the ends of the two tension bars Fand G, the upper bar, F, consisting of a rectangular bar of iron, placededgewise, strong enough to resist the tensile strain of the work to bedone and stiff enough to carry the weight of anadjustable head orupright, II. This upright II is supported on the top tension-bar, F, by,

rollers I I, and can thus be readily moved to any required distance fromtheupright A. It is securedin its position by ,keys K K, passing throughslotted holes in both bars F and G. The upright H is also notched out inits center at L to receive the axle when the machine is being used topush the axle out of the wheel, and is also convenient for receiving theprotruding end of the axle when being forced into the wheel. The ram Bhas attached to it From the above description it is evident that theessential principle of my invention consists in using the same upright Hboth for putting on and taking 011' wheels, and in using'the post-Emerely- '0 hold the tensionbars in place and to support the weight ofthe adjustable upright H. In this respect" it differs from all otherwheel-presses, which, in

' 'eneral are arran ed with an n )right in laceof the post'E strongenough to be used in pushing on wheels, while another upright, to

be used in pulling off wheels, is either placed permanently in positionneartc the upright A or can be swung into position by a crane whenneeded, thus, in the first case, being very much in the way for manykinds of work,

and, in the second case, difficult to adjust.

when required. In no instance, however, has one and the same uprightbeen used for both purposes in an upright wheel-press.

are great ease of adjustment to work of difi'erent lengths and cheapnessof construction.

I do not, however, limit my claim to the particular form of machinedescribed, for it is evident to every ingenious mechanic that it may bemodified in various ways, still retaining the same theory ofoperation-as, for instance, the rollers I I may be placed at the bottomof the upright H, to run on the lower tension-rod G, or on a bed-platewhich could be arranged in place of the lower tension-rod; but j What Iclaim as new, and desire to secure by Letters'latent, is

1. The use of an adjustable upright-,H, or its equivalent, substantiallyin the manner and for the purppse specified.

2. The hinged attachment of the blockingpiece N, or its equivalent, tothe forcing-up plunger, substantially in the manner and for the purposespecified.
